The 49ers may be without wide receiver Marquise Goodwin Sunday against the Lions after he suffered a quad contusion last week in Minnesota.

San Francisco head coach Kyle Shanahan seemed less than optimistic he'd have Goodwin at his disposal when talking to media Wednesday. Should Goodwin miss the game, rookie Dante Pettis would likely earn the start.

Pettis, a second-round pick out of Washington, hauled in two passes for 61 yards and a touchdown last week in a 24-16 loss to the Vikings. He would be third in line for targets — behind Pierre Garcon and George Kittle — should Goodwin miss the game.

The Lions were exploited through the air by Sam Darnold and the Jets last week, and star cornerback Darius Slay left the game for a while with an injury.
